How to disable 'Compile Time Image Scaling' in CIQ 4.0

Hi, is there a command line option to disable the scaling. The scaled icons look very blury / washed out and not readable in the simulator and at the devices.

e.g. the launcher icons of my widget is scaled, how can this be avoided?

The previous used padding produces much better results for the small resolution devices like the F6X.

Thanks for your hints :)
